1. How to edit monsters accuracy? (It's impossible in npc edit menu)

2. How to increase Behetmoth Stunning Fork crit. dmg?

3. How to increase every archer class crit. dmg?

Im not sure about it, but sounds logical to me that:

1. add passive skill for more accuracy
2. edit the weapon's code
3. edit/add passive skill crit damage

This should be done in the files themselves, not in-game. Im not sure if this is the exact way, I never did it, but I know its possible
